With full contact, the water on the surface of the tea absorbs heat and evaporates quickly (3-5min), achieving the purpose of fast and efficient water removal from rainwater and green tea, energy saving and low consumption. This technology breaks through the technical bottleneck of slow dehydration and high energy consumption on the surface of green leaves in rainy days, and solves the technical problem of rapid dehydration of tea rain green leaves. Apply tea rain green rapid and dynamic water removal treatment equipment to make rain green and hot air dynamic contact, accelerate the rapid removal of water on the surface of green leaves, provide suitable raw materials for tea processing follow-up processes, reduce the adverse effects of rain green on tea quality, improve Improve the quality of tea, improve production efficiency, save energy, and improve the economic benefits of tea.
